    摘要: A pressure relief valve assembly may be coupled to one or more casings and/or tubular members to control fluid communication therebetween. The valve assembly is a one-way valve assembly that relieves pressure within an annulus formed between adjacent casings and/or tubular members to prevent burst or collapse of the casings and/or tubular members. In one embodiment, the valve assembly includes a tubular body having a port for fluid communication between an exterior of the valve assembly and an interior of the valve assembly; a chamber formed in a wall of the tubular body, the chamber in fluid communication with the port; and a closure member disposed in the chamber and configured to control fluid communication through the port in response to a pressure differential.

    摘要: The present invention provides methods and apparatus for determining the location of an apparatus in a wellbore. The method includes lowering the apparatus with a conveying member and measuring a parameter associated with the conveying member. Thereafter, the measured parameter is used to determine the location of the apparatus as well as other conditions in the wellbore. The apparatus includes a conveying member operatively connected to an object released downhole. The apparatus may also include a dispensing apparatus coupled to one end of the conveying member. Preferably, the conveying member is a fiber optics line capable of transmitting optical signals. Other types of conveying members include a wire, a tube, and a cable. Additionally, a sensor may be disposed on the object and connected to the conveying member.

    摘要: The present invention generally relates to extrusion-resistant seals for an expandable tubular assembly. In one aspect, a seal assembly for creating a seal between a first tubular and a second tubular is provided. The seal assembly includes an annular member attached to the first tubular, the annular member having a groove formed on an outer surface of the annular member. The seal assembly further includes a seal member disposed in the groove, the seal member having one or more anti-extrusion bands. The seal member is configured to be expandable radially outward into contact with an inner wall of the second tubular by the application of an outwardly directed force supplied to an inner surface of the annular member. Additionally, the seal assembly includes a gap defined between the seal member and a side of the groove. In another aspect, a method of creating a seal between a first tubular and a second tubular is provided.

    摘要: A centralizer apparatus has been developed which, in one aspect, has a tubular body with an exterior surface, a collar movably emplaced around the tubular body and movable longitudinally thereon, a plurality of spring bows, each spring bow having a first end spaced apart from a second end, each spring bow biased outwardly from the tubular body, the first ends connected to the tubular body, the second ends connected to the first collar, so that upon movement of the first collar the spring bows move toward the tubular body. In one aspect the collar is connected to bottom ends of the spring bows and is initially movable to abut a stop on the tubular body so that from that point on the spring bows are pulled into another tubular, e.g. casing, as the centralizer apparatus moves down into the casing. In another embodiment two movable collars are used, one at each end of the spring bows.
